Polygonal Modeling

Edit Mesh > Merge

Merges selected edges and vertices that are within a numerically specified threshold distance of each other. For example, two selected edges will be merged into one shared edge.

Note The contents of the Merge option window changes depending on the current selection type. That is, some options are only available when either edges or vertices are selected. When no valid selection occurs the merge vertex options appear. The differences are noted below.

Merge (for edges)

These options are available for Merge when edges are selected.

Merge UVs

Merges the UVs shared by the edges. If turned off, the UVs are not merged and can be manipulated and edited independent of each other. The default setting is on. This option is available only when edges are selected.

Tip If you have a model that is mapped with different textures on either side of where the edges merge, it is a good idea to turn this option off.

Threshold

Any selected edges further apart than this distance will not be merged. Set this value carefully. If it’s too small, no edges will merge. If it’s too large, the operation may merge unwanted selected edges. The default is 0.01.

Threshold distance

World space

Specifies that the Threshold value is the distance between edges in world space. This is the default.

Local space

Specifies that the Threshold value is the distance between edges in local space.

Merge (for vertices)

These options are available for Merge when vertices are selected.

Threshold

Any selected vertices further apart than this distance will not be merged. Set this value carefully. If it’s too small, no vertices will merge. If it’s too large, the operation may merge unwanted selected vertices. The default is 0.01.

Always merge for two vertices

When two vertices are selected, the Merge feature will merge them regardless of the Threshold value. This option is available only when vertices are selected.
